when you eat a pizza so hot that you begin to breath rapidly through your mouth with the pizza cheese fused to the top of your mouth, trying to tame the burning sensation erupting on the roof for your mouth, and inadvertenly making noises like you are ahving an orgasm.

i didnt know what was going on in the other room when i heard janis making that noise, untill i opened the door only to find that she was just having a pizzagasm
